     After filling the car with gas, I continued driving to the airport. The roads were quite bumpy (颠簸) and I

noticed that the highway department was doing some reconstruction, although some parts of the road hadn't

been completed yet. I drove on a completed part of the highway that was flat and smooth for one and a half

hours. Afterwards, the road became a little rough and bumpy again, and there weren't even any street lights

on the side of the road. We started driving in the early hours of the morning and I think because it was really

early and drivers on the road were tired so they couldn't concentrate (集中注意力). I saw three separate car

accidents during the journey. 

     When starting driving in an area that I didn't know well, I let the other car lead the way and I followed

behind them. As we were driving inside a tunnel, I suddenly saw a truck hit the side of the wall, rebound (反

弹), then turned back onto the middle of the road. The truck nearly hit the car in front of us. I think the driver

of the truck must have fallen asleep at the wheel otherwise this wouldn't have happened. He nearly caused a

car accident.

     I was driving behind the cars and I saw everything happen in front of me. The incident gave me such a

fright that it immediately woke me up. In my mind I kept telling myself that I was driving a car and that I had

to stay alert (清醒). To my relief, all the members in the other car were okay because if that truck really did

hit the car traveling in front of us, I don't think I'd be able to make it back to Hong Kong. Not only that, all the

passengers in the other car would have to go to hospital.
